I’m having the same issue. When I add the variations, my formula doesn’t work. Even the variation working correctly without the WCK plugin, when I activate the plugin I get the error “Total: Select variation options first!”
Analyzing the code I noticed that when activating the plugin the div class=’woocommerce-variation single_variation’ is changed to style=’display: none;’ and I can’t change that option!
I’m using the 1.61 version of the plugin, and I tried to use the dev version without success, I don’t know what else to try.
